14 Claims. (01. 57 11c) My invention relates to fliers of the type used with spinning machines, and more particularly to a flier block arrangement having improved means for attaching and supporting the flier wires.

In Patent 2,187,862, issued to me January 23, 1940, there is disclosed a flier construction having a flier wire support member in the form of a plate adapted to fit over the head portion of the flier body or block, the plates being attached to the flier body by means of a cap positioned below the plate and attached thereto by spot welding; also in Patent 2,212,299 issued to me August 20, 1940, there is disclosed a flier construction for a bi-partite flier wire support member in the form of complementary sections having semi-circular cut-out portions adapted to seat in a peripheral groove at opposite sides of the flier block. The arms, defined by the cut-out portions, are adapted to overlap and means are provided for engagement with the peripheral flanges of the block whereby the sections of the flier wire support are securely clamped or locked to the flier block.

The present invention relates to a flier of the type disclosed in the aforementioned patents and particularly to an improved form of flier wire support member, together with means for attaching the support to the flier block. After considerable research and experimentation, I have found that the construction of my prior patents can be substantially simplified to provide improved operation and with marked economies in manufacture.

An object of my invention is to provide a flier block having improved means for attaching and supportin the flier wires thereon.

Another object of my invention is to provide a flier construction having means whereby the arms of the flier wires are supported in a fixed plane in the vicinity of their points of attachment to the flier block.

Another object of my invention is to provide an improved flier construction wherein the flier wires are attached to the flier block by twisting or entwining the arms thereof, portions of the arms beyond the points of attachment being supported in a fixed plane whereby undesirable flexing of the flier wires about their points of support is prevented.

With these and other objects in view, which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements, comprising my invention, may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical efiect, without limiting the improvelar constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawings:

Fig. 9 is a bottom plan View of the flier shown in Fig. 8.

The improved construction of the present invention comprises essentially a flier block in the form of a centrallyapertured body member having 'base and head portions, a frusto-conical peripheral flier wire support member formed on the body between the base and the head portions, and a flier wire support adapted to seat on the the peripheral edge of the upper base of the frustum. The flier wire support member, which may be formed from metal or other suitable material, is provided with a central opening adapted to receive the head portion of the block. In order to securely lock or clamp the flier wire support to the block, the body portion of the support contiguousto the central opening is formed with slits which define tongue members adapted for engagement with-the body of the block when the plate is seated inoperative position on the flier .rblock. The flier wire support is further provided with flier wire retaining means, the support and block cooperating to securely maintain the flier wires in desirable operative position.

Referring to the drawings, and more particuv:larly to Fig. l,-there is shown a flier arrangement associated with a bobbin I, mounted in operative position on a suitable spindle 2, of a conventional windingmachine. The bobbin is provided with a head member 3, and a centrally recessed portion 4 adapted to receive a ferrule 5 having an aperture Bthrough'which the flier foot l is inserted in the flier-block, designated generally by numeral 8, comprising a centrally apertured body portion -9 and a head portion IB; Between -:the base and the head portions, there is provided a peripheral flangel 1 adapted to form a seat for the flier wire support member, as will be explained more fully hereinafter.

The peripheral flange of the flier block 8,

r reference being had to Fig. 3, is substantially in the form of a frustum of a cone, the flat peripheral edge l2 of the upper base of the frustum formin a seat for the flier Wire support. It will be noted that the surface of the peripheral flange l I slopes uniformly upwardly to points just below the peripheral edge of the upper base of the frustum. In other words, the slope of the peripheral flange terminates at a line l3, the surface between this line and the peripheral edge of the upper base of the frustuim being substantially vertical to provide a, peripheral recess forming a seat for the central block engaging section of a flier wire.

Referring to Fig. 2, the flier wire support I4 is formed with a central opening adapted to receive the head of the flier block. The body portion of the support contiguous to the central opening is formed with a plurality of slits l5, defining tongue members NS therebetween. In this embodiment of the invention, the flier wire support is in the form of a metal cap having depending skirt portions I! (Fig. 4) formed with suitable notches adapted to receive the arms l8 of the flier wires. It will be noted that each of the flier wires is provided with a central block engaging portion 19, and that the arms are off-set or bent at 2% whereby the flier wires are securely clamped or locked within the slots formed in the depending skirt portions.

In assembling the flier, the flier wire support It is placed on the head portion H) of the flier block and is forced downwardly so that the tongue members it are flexed or expanded upwardly into engagement with the surface of the head portion of the block, alternate portions [6 between $110- cessive tongues remainin in substantially the same plane as the body portion of the cap and being forced into tight engagement with the upper portion of the block. After the flier wire support is attached in operative position on the block, the flier wires are attached thereto, as shown in Fig. i, the central block engaging sections iii of the flier wire being seated in the shallow peripheral groove formed in the vicinity of the upper base of the frusto-conical peripheral flange.

By means of this arrangement, it has been found that the flier wire support, together with its associated flier wire attaching means, in cooperation with the frusto-conical shaped flange provides a secure support for the flier wires and prevents rotative movement of the support with respect to the block. The flier wire support can be easily and quickly applied to the block and after it is placed in the operative position, the tongue members securely grip the head of the block so that the support cannot move in any direction with respect thereto. The flier wires can also be quickly applied to or removed from the support, and when attached to the support, are maintained in the desired operative position whereby undesirable flexing of the flier wires about their points of support is prevented.

Referring to Fig. 5, the modified form of flier wire support 2| comprises a substantially rectangular shaped member, the free ends 22 of which are slotted and turned backwardly inwardly upon themselves to form flier wire attaching means, as shown in Fig. '7. In this arrangement, it will be noted that the body portion of the flier wire support is formed with grooves 23 adapted to receive the arms of the flier wires. In order to further assist in maintaining the arms in desired separated position, the support is formed with depressed portions 24.

The flier block (Fig. 6) designed for use with the modified form of support shown in Fig. 5, is substantially the same as the block shown in Fig. 3, however, differs therefrom in that its top or head portion is formed with a peripheral flange 25, defining a groove between said flange and the upper base of the frusto-conical shaped flange. In assembling the device shown in Fig. 5, the flier wire support is placed over the head of the block and is forced downwardly thereon. The ends of the tongues or fingers l6 seat in the groove 25, that is to say, rest against the under surface of flange 25, and are pressed into engagement with the body of the block. Simultaneously with the positioning of the tongues, the body portion of the support is indented or depressed at points 2'1, and forced into frictional engagement with the block.

By means of the above described arrangement, the flier wire support is securely attached to the flier block and rotative motion therebetween is prevented. As will be seen in Fig. '7, the flier wires overlap as at 28, and the arms of the wires are maintained in desired separated position by the grooves 23 and depressed portions 24.

Referring to Figs. 8 and 9, there is shown a modifled form of flier wire support adapted for use with a flier block of the type shown in Fig. 3. In this arrangement, the support is attached to the block by means of fingers 33, which are forced inwardly against the upper head portion, whereby to lock the parts together.

While I have shown and described the preferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of illustration, as it is apparent that many changes and variations may be made therein, by those that are skilled in the art, without departing from the spirit of the invention, or
